Forecast Discussion:

It was certainly an active weather weekend, with the Tucson area picking up between 0.35 inches and 1.35 inches of rain! Rain chances have ended now that the moisture and lift have shifted east of the region. Even though rain chances are over, with plenty of moisture at the surface due to the rain, dense fog has developed, lowering visibility this morning.

Any more rain in the future? A trough of low pressure is currently moving onshore across Northern California and will sweep into the state late tomorrow into Wednesday. Unfortunately, this system will be moisture starved, so only expect a slight increase in breezes, some added clouds Tuesday and Wednesday, and no rain chances. It will, however, drop the afternoon highs into the low to mid-60s Wednesday and Thursday. A few more weak systems are expected to move through the state during the end of the week, but again you won't notice much of a change.

As for air quality, with all the rain and stabilized soils, expecting PM-10 to be in the Good AQI category through the forecast period.

Have a great Monday!
